Specification for a change output.

Implementations§

source§

impl Change

source

pub fn new(view_pair: ViewPair, subaddress: Option<SubaddressIndex>) -> Change

Create a change output specification.

This take the view key as Monero assumes it has the view key for change outputs. It optimizes its wallet protocol accordingly.

source

pub fn guaranteed( view_pair: GuaranteedViewPair, subaddress: Option<SubaddressIndex>, ) -> Change

Create a change output specification for a guaranteed view pair.

This take the view key as Monero assumes it has the view key for change outputs. It optimizes its wallet protocol accordingly.

source

pub fn fingerprintable(address: Option<MoneroAddress>) -> Change

Create a fingerprintable change output specification.

You MUST assume this will harm your privacy. Only use this if you know what you’re doing.

If the change address is Some, this will be unable to optimize the transaction as the Monero wallet protocol expects it can (due to presumably having the view key for the change output). If a transaction should be optimized, and isn’tm it will be fingerprintable.

If the change address is None, there are two fingerprints:

  1. The change in the TX is shunted to the fee (making it fingerprintable).

  2. In two-output transactions, where the payment address doesn’t have a payment ID, wallet2 includes an encrypted dummy payment ID for the non-change output in order to not allow differentiating if transactions send to addresses with payment IDs or not. monero-wallet includes a dummy payment ID which at least one recipient will identify as not the expected dummy payment ID, revealing to the recipient(s) the sender is using non-wallet2 software.
